I am a beginner in C# and creating a small game in where the user gets to throw a ball with a certain gravity, speed and random wind. The ball is supposed to hit a goal, give the user points (when it hits) and then go back to start position for user to throw it again. I have got everything working except the matter of getting the ball back into start position. Any help would be greatly appreciated!
Here is some parts of my code:
private void goButton_Click(object sender, EventArgs e)
{
if (running == true)
{
b1.Location = new Point(0, 300);
b1.speedX = (double)upDownX.Value;
b1.speedY = (double)upDownY.Value;
running = false;
b1.Start();
return;
}
running = true;
worker = new BackgroundWorker();
worker.DoWork += new DoWorkEventHandler(RunMe); worker.RunWorkerAsync();
}
public void RunMe(object sender, DoWorkEventArgs e)
{
while (running)
{
if (b1.speedY > 0 && b1.Location.Y > panel.Size.Height - b1.Size.Height)
{
b1.posY = panel.Size.Height - b1.Size.Height;
addPoints();
running = false;
BeginInvoke((MethodInvoker)delegate
{
b1.Location = new Point(0, 300);
});
}
if (b1.speedX > 0 && b1.Location.X > panel.Size.Width - b1.Size.Width)
{
running = false;
if (b1.Location.Y < 290 && b1.Location.Y > 150 && b1.Location.X > 430)
{
if (diffValue.Text == "Normal")
{
Ball.score += 10;
}
if (diffValue.Text == "Easy")
{
Ball.score += 7;
}
}
else if (b1.Location.Y < 390 && b1.Location.Y > 60 && b1.Location.X > 430)
{
if (diffValue.Text == "Normal")
{
Ball.score += 5;
}
if (diffValue.Text == "Easy")
{
Ball.score += 3;
}
}
addPoints();
b1.BounceX();
goto restart;
}
if (b1.speedX < 0 && b1.Location.X < 0)
{
b1.BounceX();
}
this.Invoke(new MoveBallCallback(MoveBall), b1);
Thread.Sleep(10);
}
}
public void addPoints()
{
if (Ball.tries >= 1)
{
Ball.tries -= 1;
string triesLeft = Ball.tries.ToString();
this.Invoke(new Action(() => this.shotsLeft.Text = triesLeft));
string score = Ball.score.ToString();
this.Invoke(new Action(() => this.scores.Text = score));
Normal();
BeginInvoke((MethodInvoker)delegate
{
b1.Location = new Point(0, 300);
});
}
else
{
MessageBox.Show("No shots left!");
string currentHighscore = System.IO.File.ReadAllText(#"highscore.txt");
this.highscoreValue.Text = currentHighscore;
int Highscore = Convert.ToInt32(currentHighscore);
string score = Ball.score.ToString();
this.Invoke(new Action(() => this.scores.Text = score));
int Score = Convert.ToInt32(Ball.score);
if (Score > Highscore)
{
MessageBox.Show("New highscore!");
string highScore = score;
System.IO.File.WriteAllText(#"highscore.txt", highScore);
string highscore = Highscore.ToString();
this.Invoke(new Action(() => this.highscoreValue.Text = highscore));
}
this.Invoke(new Action(() => goButton.Enabled = false));
}
}
You can use:
continue;
to skip to next repetition of a loop (where you write goto restart;).

the problem is that you can't assign to timespan milliseconds it's read only.
private void UpdateTime()
{
if (ticksDisplayed > 0)
btnReset.Enabled = true;
richTextBox1.Text = GetTimeString(watch.Elapsed);
optionsfile.SetKey("result", result.ToString());
}
private string GetTimeString(TimeSpan elapsed)
{
result = string.Empty;
diff = elapsed.Ticks - previousTicks;
if (radioButton1.Checked == true)
{
ticksDisplayed += diff;
}
else
{
if (countingDown)
{
ticksDisplayed += diff;
}
else
{
ticksDisplayed -= diff;
}
}
if (ticksDisplayed < 0)
{
ticksDisplayed = 0;
watch.Stop();
btnStart.Text = "START";
btnPause.Text = "PAUSE";
btnPause.Enabled = false;
if (trackBarHours.Value == 0 && trackBarMinutes.Value == 0 && trackBarSeconds.Value == 0 && ticksDisplayed == 0)
{
btnReset.Enabled = false;
}
timer1.Enabled = false;
}
ctimeSpan = new TimeSpan(ticksDisplayed);
timeTarget(ctimeSpan);
if (trackBarHours.Value != ctimeSpan.Hours) { trackBarHours.Value = ctimeSpan.Hours; }
if (trackBarMinutes.Value != ctimeSpan.Minutes) { trackBarMinutes.Value = ctimeSpan.Minutes; }
if (trackBarSeconds.Value != ctimeSpan.Seconds) { trackBarSeconds.Value = ctimeSpan.Seconds; }
result = string.Format("{0:00}:{1:00}:{2:00}.{3:000}",
ctimeSpan.Hours,
ctimeSpan.Minutes,
ctimeSpan.Seconds,
ctimeSpan.Milliseconds);
previousTicks = elapsed.Ticks;
return result;
}
calling the UpdateTime here
private void timer1_Tick(object sender, EventArgs e)
{
UpdateTime();
}
saving the timespan milliseconds is not a problem , the problem is how to read it back because you can't assign to ctimeSpan.Milliseconds.
i could save the string.Format variable result again in more places but sometimes result is null if i try to save it in the form1 closed event. so i prefer to save and load back only the ctimeSpan.Milliseconds value in that specific situation.
Editing with the full code of form1 and a screenshot.
Now i'm using the 3 trackBars to save and load the timespan hours,minutes,seconds but because i don't want to add another trackBar for the milliseconds that is the reason i want to save/load the milliseconds separated.
in my application i'm using my own OptionsFile class but it does not matter i want to find the logic and how to save/load the milliseconds separated from the way i'm saving/loading the hours,minutes,seconds.

I'm going to attempt to generalize as the question doesn't show a clear intent on what is trying to be accomplished and so it's difficult to give a clear answer.
There are many ways to instantiate a new TimeSpan as documented here:
https://learn.microsoft.com/en-us/dotnet/api/system.timespan?view=net-7.0#instantiating-a-timespan-value
If I were trying to persist and load a TimeSpan then I would personally look towards using the ticks value.
e.g.
// Create a TimeSpan to test with.
var randomTimer = Stopwatch.StartNew();
Thread.Sleep((new Random()).Next(1000,5000)); // Wait 1 to 5 second to get a meaningful value in the example TimeSpan.
var myTimeSpanToSave = randomTimer.Elapsed;
// Save the total ticks here.
var totalEllapsedTicks = myTimeSpanToSave.Ticks;
// Load total ticks and instantiate a new TimeSpan
var newTimeSpanFromTicks = new TimeSpan(totalEllapsedTicks);
I'm not sure why you would want to modify just the Millisecond portion of a TimeSpan but assuming there is a valid reason then here are a couple of ideas.
Idea 1 - Create a new TimeSpan using the values from the original object and substituting the Millisecond property only.
var customMilliseconds = 123;
var newTimeSpanWithCustomMilliseconds = new TimeSpan(myOriginalTimeSpan.Days, myOriginalTimeSpan.Hours, myOriginalTimeSpan.Minutes, myOriginalTimeSpan.Seconds, customMilliseconds);
Idea 2 - Use Add to clear the current Millisecond value and insert the loaded value.
var customMilliseconds = new TimeSpan(0, 0, 0, 0, 123);
var oldMillisecondValueToRemove = new TimeSpan(0, 0, 0, 0, myOriginalTimeSpan.Milliseconds);
myOriginalTimeSpan.Add(-oldMillisecondValueToRemove);
myOriginalTimeSpan.Add(customMilliseconds);
I am making a DxBaLL Game. First i tried make the ball with picturebox but when it comes to intersection, if ball interects with 2 bricks, bricks just break but i want them break in 3 shots. So then, i tried make ball with Graphics.DrawEllips but how can i detect if ball intersect with picturebox(brick) or not?
This is the ball with picturebox version. when the ball comes between 2 bricks(picturebox), bricks are disappearing.

Try changing the name of your "score" variable, try calling it like, "myScore", typically if something is ambiguous it is because there are two fields or properties with the same name in assembly references that are not directly specified in the code.

So, I'm making a game which is kind of similar to pac-man and I want to add a reset-button (resetting the game, NOT restarting the application). I've tried a lot of things but I still can't get it working. Any solutions?
Thanks in advance,

Just create a new instance of Game. This will give you a whole new set of variables and therefore a new game state.
You need to keep a reference to the game to keep it from being GC'd, so you also need a static variable.
static private Game _currentGame;
private void ResetButton_Click(object sender, EventArgs e)
{
this.Hide();
_currentGame = new Game();
_currentGame.Show();
this.Close();
}
I dont know how to make ball bounce when hits Paddle´s Top or Bottom, my problem is that the ball goes through the Paddle and then keep going...
So this is the code, some things are in my language so here is translator:
Mustek = Paddle
Mic = Ball
body = Points
HraciPole = Name for graphics array, something like "GameArray"
casovac = name for timer
Kolize = Collision
PohybDolu = MoveUp (bool)
PohybNahoru = MoveDown (bool)
public partial class Form_Pong : Form
{
public static Mustek p1 = new Mustek();
public static Mustek p2 = new Mustek();
public static Mic ball = new Mic();
public int body1 = 0;
public int body2 = 0;
Graphics draw;
public Form_Pong()
{
InitializeComponent();
draw = picBoxHraciPole.CreateGraphics();
}

The basic logic that you are looking for is
If edge of ball =edge of paddle then change direction so as if x was decreasing bow x is to ve increasing
Once you have that you can work out angles for different conditions such as if it gits the edge of the paddle ect.
